At a candy store, Erika bought 3 kilograms of cinnamon red hots and 1 kilogram of gummy bears for $21.00. Meanwhile, Irene bought 3 kilograms of cinnamon red hots and 3 kilograms of gummy bears for $39.00. What is the cost of one kilogram of each type of candy?

Answers

Answer 1

Answer: Taking the difference of the both you can see that 2 kg of gummy bears would cost $18. So each kg of gummy bear is $9. Now subtract $9 from what Erika bought, and 3 kg of red hots are $12. So each kg of red hots are $4.

Which angle is an x-intercept for the function y = cos(1/2x)

Answers

For the function
y = cos(1/2 x)
The x-intercept can be calculated by equating the function to zero and solving for x. So,
y = cos(1/2 x) = 0
1/2 x = arc cos 0
1/2 x = 90° +180°n
x =2 (90° +180°n)
x = 180° + 360°n
or converting to radians
x = (180° + 360° n)(π/180°)
x = π + 2π n
where n is any whole number

if n = 0
x = π

Therefore, the x-intercept is π or π+2π n

3x + y = 17 and 4x - y = 18

Answers

I'm not sure if this is what you're asking for but here goes...
3x + y = 17
+ 4x - y = 18
———————
7x = 35
x = 5

sub x = 5 into eq. 1
3x + y = 17
(3 × 5) + y = 17
15 + y = 17
subtract 15 from both sides of the equation.
y = 2

Final Answer - ( 5 , 2 )

The radius of a circle is 6 yards. What is the circle's circumference? Use ≈ 3.14 and round your answer to the nearest hundredth.

Answers

Answer:

C = 37.68 yards.

Step-by-step explanation:

To find the circumference of a circle, you can use the formula C=2πr, where C is the circumference, π is a constant that is approximately equal to 3.14, and r is the radius. Plugging in the given value of r=6 yards, we get:

C=2×3.14×6

C=37.68

Rounding to the nearest hundredth, the circumference is 37.68 yards.
